Abstract:Valve cooling system plays an important role in DC transmission engineering. The current control and protection systems still lack the ability to make predictive judgments on potential faults in valve cooling equipment, and there is an urgent need to strengthen effective monitoring of equipment through digital means. Based on the experience of existing digital pilot stations, this paper introduces the data sources of the digital platform, and at the same time, aiming at the shortcomings of the lack of intelligence in existing valve cooling control and protection equipment, it proposes applications of digital technologies such as data analysis prediction, health assessment of the main pump, health assessment of the valve cooling system, leakage warning, and fault diagnosis, to reduce the operating costs and fault handling time of converter stations, and improve the operational reliability of the power grid.
